Data compression device allowing detection of signals of diverse wave forms

ABSTRACT

The data compression device allows detection of signals of diverse wave forms and also recording of the time and number of their next appearance. In particular, the Information Compressor includes an analog-to-digital converter with a data processor connected to it. A controller is interconnected to the data processors and also to the analog to digital converter. A signal detector may be interconnected with the data processes and the analog-to-digital converter and it is also preferable for a control console to be provided.

FIELD OF THE INVENTION

This invention relates to information, measurement and computer technology, and more specifically to data compression devices.

BACKGROUND OF THE INVENTION

Currently, many studies of brain heron systems activity employ multineuron activity recording techniques. To this end computers with large memory capacity are based, but even this fails to provide the required efficiency of detecting rapidly varying signals with multiplicity of diverse waveforms.

Known in the art is a data compressor (SU,A,1101832), comprising an analog-to-digital converter with the input thereof constituting the compressor input, a data processor with the data inputs thereof connected to the analog-to-digital converter output via a data bus and with the outputs thereof constituting the compressor outputs, and a controller with the control input thereof interconnected with the control input of the data processor and connected to the control output of the analog-to-digital converter, with the other input thereof connected to another outputs of the data processor, with the control output thereof connected to yet another control input of the data processor and with the address output thereof connected via the address bus to the address input of the data processor.

This known in the art data compressor compares each current sample of the signal to the preceeding sample and therefore, if a sample is repeated, it is recognized as a new signal, i.e. the compressor passes a signal even if it repeats the waveform of the preceeding signal. This significantly reduces compression efficiency when solving problems of detecting interrelations between rapidly varying signals of diverse waveforms, if the number of possible waveforms is rather small.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide an information compressor having such additional units that would allow detection of signals of diverse waveforms, and recording the time and number at their next appearance.

The other input and the output of counter 154 (FIG. 8) constitute, respectively, input 26 and output 36 of controller 23.

The information compressor functions as follows.

A reset pulse from output 56 (FIG. 1) of control console 47 arrives at input 50 of signal detector 6 and at inputs 52, 53, 54 of data processors 10, 11, 12, respectively. Thereafter, the noise level code, the signal end code and the aperture code are set on console 47 and are transmitted from outputs 48 and 49 to inputs 45 and 46, respectively, of signal detector 6 and from output 61 to inputs 57, 58, 59 of data processors 10, 11, 12, respectively. An analog outside signal is applied to input 2 of analog-to-digital converter 1, wherein it is digitized and passed from output 3 via data bus 4 to data input 5 of signal detector 6 and to data inputs 7, 8, 9 of data processors 10, 11, 12, respectively. Simultaneously with data from converter 1 a "conversion completed" signal from output 31 is passed to input 25 of signal detector 6, to inputs 27, 28, 29 of data processors 10, 11, 12, respectively, and to input 26 of controller 23. Thereafter signal detector 6 compares the noise level code to the data code, and, if the data signal is within the noise level band, a logic "0" is generated at output 44 of signal detector 6, passed to input 43 of controller 23 and inhibits the controller. If the data signal is above noise level, a logic "1" is generated at output 44 of signal detector 6, passed to input 43 of controller 23 and enables controller 23.

The address code of the signal from converter 1 is set on address bus 35 by output 36 of controller 23 and passed to inputs 32, 33, 34 of data processors 10, 11, 12, respectively. Simultaneously with the address code, controller 23 sets the control code at its output 24, passed to inputs 19, 20, 21 of data processors 10, 11, 12, respectively, wherein data from output 3 of converter 1 is read out at a transition from "0" to "1" or written at a transition from "1" to "0". On the next arrival of data from output 3 of converter 1 at inputs 7, 8, 9 of data processors 10, 11, 12 a "0" to "1" transition causes simultaneous readout and comparison of the data in all data processors 10, 11, 12.

If the received data differs from data previously written by more than the aperture set, it is entered into data processor 10 and thereafter this process is continued. In case the signal from the analog-to-digital converter differs from that written into data processors 10, 11, 12 by less than the set aperture, at output 37, or 38, or 39 a number will be generated, indicating the data processor 10, or 11, 12, wherein signals identical to that just received are stored. Simultaneously the number code from output 37 (or 38, or 39) is sent to input 41 of controller 23, where the time of repeated signal appearance is recorded. This process is repeated until the memory of data processors 10, 11, 12 is filled. Thereafter the signals entered are serially read out from outputs 14, 15 and 16 of data processors 10, 11, 12.

Data processor 10 (or 11, or 12) functions as follows.

Input 52 (FIG. 2) of control circuit 69 receives a reset pulse from control console 47, input 57 of comparator 62 receives the aperture code from control console 47, input 65 of comparator 62 and input 66 of working memory 64 receive data from analog-to-digital converter 1, and input 63 of comparator 62 receives a signals from output 14 of working memory 64. In comparator 62 the data from analog-to-digital converter 1 is compared to the signal received from working memory 64 and the difference between these signals is compared to the aperture code. If the set aperture is greater or less than this difference, different logic levels are generated at outputs 67, 68 of comparator 62 and control circuit 69 generates an enable signal at its output 77, passed to input 78 of working memory 64. Simultaneously, the address code of the received signal arrives at input 32 of working memory 64 and control signals arriving from controller 23 at input 19 of control circuit 69 and from analog-to-digital converter 1 at input 75 of working memory 64 and at input 74 of control circuit 69 enter the received data into working memory 64.

If the aperture is equal to the difference between the data received from analog-to-digital converter 1 and the signal from working memory 64, two identical logic signals are generated at outputs 67, 68 of comparator circuit 62, thereby causing an enable signal to be sent from output 79 of control circuit 69 to input 81 of read-only memory 80, which generates a signal number code at its output 37. A signal inhibiting data writing into working memory 64 arrives from output 77 of control circuit 69. Thereafter the process is repeated.

Comparator 62 in data processor 10 (or 11, or 12) functions as follows.

Input 65 (FIG. 3) of adder 82 receives data from analog-to-digital converter 1 to be compared with the code signal at its input 63. The difference from output 83 of adder 82 is passed to input 85 of adder 84, wherein a logic signal is generated at output 68 to be applied to input 89 of multiplexer 87, the other input 57 whereof receives the aperture code from control console 47. Depending on the signal at input 89, multiplexer 87 sets the aperture in the direct or inverse code and passes this signal to input 86 of adder 84, to generate a difference signal at its output 67.

Control circuit 69 (FIG. 2) in data processor 10 (or 11, or 12) functions as follows.

Inputs 70 and 71 (FIG. 4) of comparator element 89 receive the signal from adder 84 (FIG. 3) in comparator 62 (FIG. 2). Comparator element 89 (FIG. 4) generates a logic "0" at its output 90 if the signals are equal, passed to input 92 of OR gate 91, input 93 whereof simultaneously receives a signal from output 95 of comparator element 94 with input 72 thereof receiving a signal from working memory 64 (FIG. 2) and other input 100 thereof receiving a control pulse from controller 23 (FIG. 1). One of the signals arriving at inputs 92, 93 of OR gates 91 (FIG. 4) is passed from its output 96 to input 98 of flip-flop 97, the other input 52 whereof receives a reset pulse from control console 47 (FIG. 1) to reset flip-flop 97 (FIG. 4). The signal from output 102 of flip-flop 97 is passed to input 105 of NOT gate 104 and after inverstion is passed from its output 77 to input 78 of working memory 64 (FIG. 2). The signal from the other output 103 (FIG. 4) of flip-flop 97 arrives at input 107 of logic AND gate 106, input 19 whereof receives a control signal from controller 23 (FIG. 1) and in case of a logic "1" at input 107 the control signal from its output 79 is again applied to output 13 of signal detector 6 (to the compressor input).

Signal detector 6 functions as follows.

Input 50 of signal/noise comparator 108 (FIG. 5) receives a reset pulse to reset comparator 108. Input 5 of signal/noise comparator then receives data and input 45 thereof receives the noise code for comparison, the result being gated by synchronization pulses at input 114 to generate a reset signal at output 110 passed therefrom to input 113 of signal end detector 111 to reset the signal and detector. An enable signal is passed from output 109 of signal/noise comparator 108 to input 112 of signal end detector 111 to remove the inhibit from input 113 thereof and thus pass gating pulses to signal end detector 111. Input 115 of signal end detector 111 receives the signal end code from control console 47 (FIG. 1). After comparing the time of signal end to the gating synchronization pulse, a control signal is generated at output 44 of signal end detector 111 (FIG. 5) passed to controller 23 (FIG. 1) and to input 117 of signal/noise comparator 108 (FIG. 5). This signal sets signal/noise comparator 108. The signal generated at output 13 of signal end detector 111 is passed to the compressor output.

Signal/noise comparator 108 (FIG. 5) functions as follows.

A reset pulse arrives at input 50 of flip-flop 119 (FIG. 6) and at input 125 of flip-flop 122.

Input 45 of adder 118 receives the noise level code and input 5 of adder 118 receives data, for comparison in signal/noise comparator 108. If the data level is below that of noise, a logic "1" is set at output 121 of adder 118, inhibiting passage of synchronization pulses arriving at input 25 of flip-flop 119 and the latter remains in its initial state.

If the data level is above that of noise, a logic "0" is set at output 121 of adder 118, enabling passage of synchronization pulses arriving at input 114 of flip-flop 119 and switching it to the logic "1" state, i.e. setting a logic "1" at flip-flop 119, output 109 to be passed to input 123 of flip-flop 122 and simultaneously to output 109 of signal/noise comparator 108, setting a logic "1" at output 110 of flip-flop 122.

Signal end detector 111 functions as follows.

An enable signal from signal/noise comparator 108 arrives at input 113 of logic AND gate 130 (FIG. 7), along with a synchronization pulse at its input 46. If the enable signal is a logic "1", synchronization pulses are passed to output 131 of AND gate 130 and arrive at input 133 of counter 132. At the same time input 112 of counter 132 receives an enabling signal and the time code arriving at input 136 of adder 135 is set at output 134 of counter 132, with the signal end being set by a signal from control console 47 (FIG. 1) arriving at adder 135 input 136. The result of comparison is passed from output 137 of adder 135 (FIG. 7) to input 139 of logic AND gate 138 and from the output 140 thereof to input 142 of logic NOT gate 141, the inversed signal from the output whereof arrives at input 144 of delay element 143 and simultaneously is the output 13 of signal/noise comparator 108 (and also the output 13 of the information compressor). A set signal is generated at output 44 of delay element 143 and is passed to set input 117 (FIG. 5) of signal/noise comparator 108, setting this latter to its initial state.

Controller 23 (FIG. 1) functions as follows.

A reset pulse is applied to input 156 of main counter 147 (FIG. 8), to decoder 150 input 157, and to supplementary counter 154 input 155, setting them to their initial states. Input 26 of counter 154 receives synchronization pulses to set the address code at its output 36, passed to address inputs 32, 33, 34 of data processors 10, 11, 12, respectively. The signal number code from outputs 37, 38, 39 of data processors 10, 11, 12, respectively, arrives at input 41 of signal detection circuit 145 (FIG. 8), and input 43 receives a control pulse from signal detector 6. A code signal from output 149 of counter 147 arrives at input 152 of signal detection circuit 145 and is compared to the channel number code. In case of coincidence a control pulse is generated at output 146 of detection circuit 145 and is passed to input 148 of counter 147, to change the code signal at output 149 thereof. This signal arrives at input 151 of decoder 150 to generate a control signal at output 24 thereof, passed to control inputs 19, 20, 21 of data processors 10, 11, 12, respectively. In case the code at input 152 of signal detection circuit 145 differs from the channel number code, the control signal from output 146 of signal detection circuit 145 is not passed.

This invention provides independence of the data compression ratio from the rate of input signal variation, thus allowing passage to the output at low speed of rapidly varying signals, such as spikes, during studies of brain multineuron activity.

Industrial Applicability

The invention can be used for data compression in multichannel telemetry systems with time-division multiplexing.

Moreover, the invention provides reception of analogue electric biplar signals, their digitization, classification and transfer to a computer via a communications channel.

This invention is also intended to enter multineuron activity signals to a computer and can be used in any information transmission system to interface high infromation-content sources with the input channel of a computer.
